Outline The impedance meter KFM2005 is designed for testing of the fuel cell with the small current (5 A or less), and not only the current-voltage characteristic test, the KFM2005 can easily measure for the impedance of a fuel cell using the AC impedance method, and the Cole-Cole plot. Using the measurement data of the Cole-cole plot, it is possible to calculate the circuit constant of the approximate equivalent circuit of the fuel cell. The built-in DC load (60W) is capable to operate from 0 V, and it can perform the test for the fuel cell up to 20V and 5A. Features Impedance of cells up to 20V can be measured in the range of 10 mHz to 10 kHz. (The cell voltage/current can be read back as well in the 0 V to 20 V / 0 A to 5 A range.) Impedance measurement. (The measurement AC current can be set for the range at 10% to 100% of each range of the rated value in 0.1% step. ) (Impedance measurement under condition of measurement AC voltage at 5 mV applied by the dummy constant voltage can also be set. ) Built-in electronic load offers two constant current modes ranges for the load rating: 5 A and 0.5 A Load current setting resolutions of 0.1 mA (5 A range) and 0.01 mA (0.5 A range), with maximum power consumption of 60 W.
